ERASING SHIELD.

Application filed May 6, 1921.

To all whom it may concern:

Be it known that I, MILLARD EDMUNnsoN, a citizen of the United States, and a resident of the city and county of San Francisco,

tate of California, have made a new and useful invention-to wit, Improvements in Erasing Shields; and I do hereby declare the following to be a full, clear, concise, and exact description of the same.

This invention relates particularly to an improved erasing shield for use on typewriters.

An object of this invention is to provide an erasing shield that may be handily used by an operator of a typewriter so as to permit printed impressions being more easily. neatly and efliciently removed and that will eliminate or minimize the possibilities of smudging or smearing carbonized impressions on any sheets under the original record sheet.

A further object of the invention is to provide an erasing shield that will be superior in point of simplicity and inexpensive ness of construction, positiveness of operation, facility and convenience in use and general eiiiciency. Other objects and advantages will appear as this description pro gresses.

In this specification and the annexed drawings, the invention is illustrated in the. form considered to be the best, but it is to be understood that the invention is not limited to such form, because it may be embodied in other forms, and it is also to be understood that in and by the claims follow ing the description, it is desired to cover the invention in whatsoever form it may be embodied.

In the accompanying one-sheet of drawings,

Figure 1. represents a perspective view of an erasing shield constructed in accordance with my invention.

Figure 2 represents a side elevation of an erasing shield constructed in accordance with my invention appliedto the platen of a typewriter.

In detail the construction illustrated in the drawings comprises a sheet of metal, or composition of other desirable nature, hav ing a body portion 1 thereof curved or formed on the arc of a circle struck on substantially the same radius as that of a rubber cylinder or platen of a typewriter. I do not wish to limit the curve of the body portion 1 of the erasing shield to that of an Specification of Letters Patent.

Serial No. 467,396.

arc of a circle as it would be clearly within the purview of this invention to modify the same to a form either slightly parabolic or hypobolic. An end 2 of the curved body portion 1 is bended at anangle thereto. The portion 2 is preferably bended at an angle of substantially ninety degrees to that of the face of the curved portion 1 and thus provides a suitable finger grip for the operator in applying or removing the said shield to or from the platen of a typewriter.

It is desirable that the faces of the finger grip 2 be suitably roughened at 3 so as to afford a firm grip to the fingers and furthermore it is intended to magnetize the shield when it is made of metal, so that it can be placed upon any accessible part of the typewriter frame in constant readiness for use.

The inner curved face of the body portion 1 has a flexible and resilient composition 4 fixed thereon of either rubber, felt or some equivalent thereof. The purpose of applying the flexible composition to the shield will be obvious as it would rest upon the back face of a carbon sheet used for duplicating copies of the original record sheet, thus preventing smudging or smearing on the copy where the operator would remove an erroneous impression or otherwise correct a-nv subject matter appearing upon the original record sheet.

Having thus described this invention. what I claim and desire to secure by Letters Patent is:

1. An erasing shield compris ng a body portion formed on the arc of a circle; an end formed at substantially right angles thereto and a resilient composition on a face of said body portion.

2. An erasing shield comprising curved body portion; a finger grip extending ,qularly from said body portion and a resilient composition on one side of said curved body portion.

3. An erasing shield comprising a curved body portion, a finger grip extending angularlv therefrom and having roughened faces thereon and a resilient composition fixed. to the inner curved face of said body portion.

In testimony whereof. I have hereunto set my hand at San Francisco, California, this 14th day of April, 1921.

MILLARD EDMUNDSON.
